Circumstances: They were abducted by their non-custodial father, Gary Joseph O'Brien. A photo and vital statistics are posted below. He typically had visitation with them on Saturdays and on the above date their mother, Diane Boland, advised him Mitchell was ill and suggested he stay at home instead of going. He told her to have all three ready to visit with him. He called her at 8:30 in the evening and told her that he was not returning the boys and had built a trap in his home that would explode when someone entered the residence. His house was found to be rigged with a propane fuelled bomb that could have destroyed the whole neighborhood. He had previously threatened their mother by telling her she would not see her children again. Felony warrants are on file for him for kidnapping, attempted murder, and crimes against life and health. They may be in the United States. They may be traveling in a gray 1989 Ford Tempo with Newfoundland license plate AMX 635. In 1997 the engine from a 1989 Tempo was found in the ocean off a cliff near Torbay. It is not known whether it was from Gary's car or if anyone was in the vehicle at the time. Caution is advised.
